ORTOVOX's Fleece Light Grid ZN Hooded Jacket is one of their lightest, delivering high mountain warmth without weighing us down. Merino Fleece Light Grid keeps merino wool next to the skin for moisture management and reduced odor build-up, plus the waffle structure enhances airflow and delivers a high level of heat retention. Synthetic fibers boost durability and improve wicking for active comfort. And speaking of activity, the slim fit matches our body movements, and the close-fitting hood layers comfortably under a helmet.
